Oh, I missed that!

Well, there is no instruction boundary at either of those addresses. Either
the register dump is bogus or somehow we ended up jumping into the middle of
an instruction inside vmxassist. Bogus. :-(

You could try initialising the traceset variable in vmxassist/vm86.c to ~0
instead of 0. That should get you a whole load of extra tracing about
exactly what vmxassist is emulating and where. We might be able to work out
a bit more from that.
